Interesting - the Jack screw brackets were tight in my case - the slack was in the gear housing. I put the rubber washer on the wrong side of the housing (it should be on the cover side - opposite the nylon washer). Put the rubber washer in and the majority of the slack was removed and it...
Ok - rebuilt my driver and passenger seat gears and it is working fine. However - the jack screw that bolts to the adjuster motor housing has some slack. like 1/8" of play sliding forward and back only on the driver side. All bolts and connections are tight.
While I rebuilt gear boxes of...
Off my 1997 FJZ80 with ABS tone rings. About 230K miles on them. I purchased truck with 190K about 6 years ago.
Got new ones in preparation for a long road trip. They seemed to be fine - just overzealous on front axle rebuild I guess.
You pay for shipping and they will be yours. Just...
Alright - got my issue fixed! I didn't replace the brass spindle bushing when I rebuilt the knuckles. Bad bushings - new bushing/roller bearings installed. Runs and sounds fantastic!
What was the resolution to this? This noise just appeared on my 80 after full front Birfield replacements with bearings etc.... Had a little noise like this for years very minor and short in duration, but after a 600 mile drive on highway now noise is very noticeable. I had both drive lines...
I just replaced my birfields and flanges. 1997 FJ80. They functioned fine - a little clicking. Probably original - 230K miles. Selling both plus flanges.
Replaced motor - sorry that I didn't see your post slow95z. Picked it up today from shop and the used motor had 91K on it - zero sludge and runs perfect. Came with a 5 year/50K warranty. Sounds very quiet and runs like a Swiss watch. That was expensive though.....really expensive :(
Main bearings, pistons, cylinder walls, crank, etc.... Not even sure what the valve guides look like. It was amazing that compression and leak down were still ok and oil pressure was ok. A testament to the durability of the engine. The shop that works on these a lot said they've never seen...
Well - catastrophic failure. Apparently some oil channels were blocked in the head - loss of lubrication, loss of pressure to chain tensioner and poof......
Shop cleaned out ports and clacking sound reduced considerably - but the damage was done.
Suspect that when the PO rebuilt head there...
I'm having this exact same sound coming from my engine - figure it out yet? My shop is stumped and my journey is just beginning. Good tips in here so far.
Dealer installed new chain tensioner, oil change with OEM filter. No change. They had sympathy for me and charged a minimal amount - which was nice of them. Dealer is at a loss and suspect is deeper in the engine than the top end - I'm not going to spend thousands in this rabbit hole...
Oil pressure was done via an inline test at Toyota dealer. Cover is currently off - the dealer checked clearances of the valves. The word was that the "cam gear spring" was fine but it's worth asking again about the tensioner. Those are good tips.
I'm now reading a lot about cheap oil...
